What does a heater hose connector do?

A heater hose is a rubber hose used in automobiles, and it transports hot coolant to the heater core. The heater hose connects to the water pump and the heater core, which is located next to the firewall on most vehicles.

Do heater hoses hold coolant?

Will my AC still work if I bypass my heater core?

Without going into a full system rebuild, keeping what you have topped off and clean would be the only things you can do. Bypassing the heater core shouldn’t affect the ac system since it should have a valve that closes off flow to the core when its not being used anyway.
